Thanks, I remember the thread now. It makes sense.

I tried to switch to pass-by-value:

struct X
{
    template<class T> explicit X(T);
    template<class T> X & operator= (T);
};

... and received all kinds of weird results from the compilers. Only g++
2.95.2 works as I expect, preferring the implicit copy constructor and
assignment operator over the template versions.

Back to the drawing board.
